Re: Multithreaded failure

2002-04-08 Thread Paul . Hussein 


Thats not the only problem. I get problems when loading an image when
multithreaded. As previously posted.

If I could build the darn thing, I might look into fixing it.

I moved the creation (and destruction) of the Driver object inside the
method.  Also I had forgotten that in Apache SOAP, you can control object
lifetime.  So I changed it from Application to Request, so now each request
gets a fresh instance of my class.

This works, but I'm not happy with it.  My question is this, if I have a
Driver object as a global inside my class, will it be trounced by another
instance running in a different thread?

Have you tried with jdk1.3 ?
Maybe  './build.sh -debug' gives some more info.

 Paul.

RE: Multithreaded failure

2002-04-04 Thread Scott Moore 

Why are you reading the user configuration more than once?  In my servlet,
which is multithreaded, I read the user configuration file once upon init.
I have no problems (except the occasional image error, which I catch and
regenerate the PDF when it happens) with concurrent PDF generation using
FOP.

You can see where the second thread enters because of the double entry for
reading user configuration file, then the repeated failed starts.  After
each setting up fonts, is where the exception is being thrown.  Just to
make sure, I am using Xalan from CVS, as per a suggestion from someone on
the Xalan list.

Simply because it is at the top of my SOAP method.  I don't think that there
is an init() called on a SOAP class.  Also, do you instantiate a new Driver
object for every call to the servlet?  I'd appreciate if you could share
some code.  Thanks.
